Title: Temperature control system for textile tenter frame apparatus
IPC: F27B9/28
Filed: 1976-01-28
Abstract: 1500634 Automatic control MEASUREX CORP 28 Jan 1976 [18 June 1975] 3430/76 Heading G3N The automatic control system of a tenter frame apparatus predicts, in response to the temperatures of moving fabric and bulk air within the tenter frame and the speed of the frame, a "time-attemperature" value which is compared with a preselected target value to provide an output signal for controlling frame speed. As shown, a tenter frame 32 comprises a conveyer 36 on which a fabric to be dried is transported on a conveyer 36, having two parallel belts each driven by a motor 44 the speed of which is so controlled that the fabric is maintained above a heat-set temperature for a desired time. The motor speed is computed in a digital processor 52 in response to the outputs of sensors 56, responsive to fabric temperature, and of a sensor 58, responsive to oven temperature. The outputs are interfaced to the processor through an A/D converter 56 and fitted to a desired curve by an algorithm represented by the section 66. Target temperature is set in by an operator panel 64 to a section 68 and the predicted time-at-temperature summated with a desired time-at-temperature from panel 64 in a section 70. The conveyer speed change is calculated in a section 72 a modified in a summating section 74 by the output of a moisture gauge 50. The resulting output is fed to a conveyer speed control section 76 receiving a feedback signal from a tachogenerator 62 and controlling the motor 44 through an interface 60 and a servocontrol 46.
Patent GB-455887-A (GB)
Title: Improvements in or relating to sliding clasp fasteners
IPC: G09F19/18
Filed: 1936-02-05
Abstract: In a process for varnishing sliding-clasp fasteners, varnish is applied in the thinnest possible layer to the cleaned fastener elements, the elements are then partly dried, are then separated from one another by tossing, tumbling centrifuging or the like, and this treatment is repeated several times, preferably ten times or more. In an example, the fastener elements are cleaned in dilute hydrochloric acid, and washed in water and in benzol.  A charge of the cleaned elements is introduced into a rotary drum, and varnish is sprayed thereon.  The elements are then dried at 100--110 DEG  C., for 1 or 2 hours, and separated in a tumbling box. This sequence is repeated about 15 times.  After the last coating the elements are fully dried at 140--170 DEG  C., for 3 to 8 hours. The elements are preferably heated again to about 90 DEG  C., before they are pressed on to the stringer, to avoid cracking of the coating, or the final drying may be effected after such attachment.  The slider element may be varnished in any usual manner, its interior being kept free from varnish by the insertion of a thin plate between its jaws.

Title: Improvements in or relating to call-recording arrangements in telephone or like systems
IPC: H04M15/38
Filed: 1938-02-04
Abstract: 498,374. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Feb. 4, 1938, No. 3579. Convention date, March 10, 1937. [Class 40 (iv)] In a system employing automatic ticketing machines, the tariff is recorded in monetary values in accordance with the zones of the calling and called parties. As shown, an incoming selector, Fig. 1, at a central exchange is associated over finders JF, CF with a tariff determining circuit, Fig. 2, and with a ticketing machine, Fig. 4. Test relays Cn, Ct (not shown) of the finders operate, connecting up Ri, Pw, and impulses are repeated to the register switch ST and to the digit wheel magnet DPM. The relapse of Lm, at the end of the first digit connects up Ed, whereupon Df energizes and operates the magnet CM which rotates a shaft MCS through one revolution to effect printing. Relays Ri, Pw fall back temporarily and release Ed, and the sequence switch SD moves to position 2 in which Ef pulls up and prevents further stepping of ST. Relays Lm, Ed, however, respond to the remaining digits and control printing. In position 5 of SD, Ed connects direct ground instead of resistance ground to energize marginal relay Nf as well as Df, so that the magnet CM operates independently of Ri and rotates the shaft MCS through several revolutions corresponding to blank positions on the tape until cams CS (which move forward at each revolution of MCS) reach position 10. Relays Ri, Pw re-operate and connect up Ic, Bd (SD being in position 6), whereupon relay Ih is controlled by an interrupter to send impulses to the digit wheel magnet DPM and to the counting switch SC. One of the wipers of the register switch ST is chosen in accordance with the zone of the calling party by the position of the finder JF, the terminals of corresponding junctions being jumpered together at Z 1-3, and the banks of ST are cross-connected to relays Tf. Ot which mark stopping positions of SC in positions 6-9 of SD. Relay Ed responds when a stopping position is reached, restoring SC and effecting printing as described above. In the example shown, the tariff expressed in francs and centimes is 0-80 with Tf, Ot both inoperative, 1-20 with Ot operated and 2-00 with Tf operated. The tariff determining circuit then releases. If more than one digit is required to determine the zone of the called party, several register switches ST and a translating switch would be employed. The zone of the calling party may be determined by a signal or a digit received over the junction. Specification 472,434 is referred to.
